FN nanofibers were prepared by adapting the SIA approach described previously.20 , 21 (link) Briefly, poly(dimethylsiloxane) (PDMS) stamps for microcontact printing, patterned with either 1 cm long, 50 µm wide raised lines or 1 cm long, 10 µm wide raised lines were fabricated by first spincoating glass wafers with SPR 220.3 positive photoresist (Microchem). The photoresist was then exposed to UV light through a photomask and developed using MF-319 developer (Microchem). A negative of the patterned photoresist wafer was formed by casting PDMS prepolymer (Sylgard 184, Dow Corning) over it and curing it at 65° C for 4 hours. The cured PDMS was then peeled off the glass wafer and 1 cm2 stamps for microcontact printing were cut out.

Polydimethylsiloxane (PDMS) stamps for microcontact printing consisting of an array of 20 μm wide, 200 μm long rectangles were fabricated according to published methods.21 -23 (link) Briefly, glass wafers were spincoated with SPR 220.3 positive photoresist (Microchem), exposed to UV light through a transparency-based photomask and developed using MF-319 developer (Microchem). Sylgard 2184 PDMS (Dow Corning) was then mixed in a 10:1 base to curing agent ratio, mixed and degassed and then poured on the patterned photoresist and cured at 65°C for 4 hours. PDMS were then cut out and sonicated in a 50% ethanol solution for 45 minutes and dried under a stream of nitrogen.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
